Martin Audio AM12

Stadium Series


As part of the commercial installation range, the Stadium Series provides the contractor with a range of environment specific loudspeakers that integrate seamlessly for use in any sports facility, stadium or arena where high SPL, excellent intelligibility and weather resistance are of prime importance.


The AM Large Format Horns have a stiff, lightweight core of high-density expanded polystyrene, covered with a thermoplastic skin which has an exterior grade coating to increase durability and protection from UV. All other AM enclosures are constructed from marine ply and coated both internally and externally with a textured high-density polyurethane coating. The waterproof cone drivers are protected by heavy-galvanised and polyester-coated punched steel grilles fitted with an integral water barrier.


Martin Audio Stadium Series – performance with safety in mind.

The AM12 is a 2-way passive enclosure that has been specifically designed for applications such as stadiums and arenas where high SPL and weather resistance are of prime importance. The AM12 has a 300 watt 12" (300mm) direct radiating reflex loaded low frequency transducer with a waterproof cone coupled with a 1" (25mm) exit HF compression driver mounted on a rotatable 80º horizontal x 50º vertical constant directivity horn. The enclosure is of a vertical trapezoid design and horizontally formatted to reduce sightline obstruction.
